| description | A power supply having a transformer, a magnetizing current regulation circuit, and a device for controlling the regulation circuit intended to switch the regulation circuit alternately from the magnetizing state to the demagnetizing state is disclosed. The control device is intended to prolong the magnetization phase for a magnetization time (TF). The power supply also includes an output capacitor connected to a secondary of the transformer so as to form a resonant circuit with the leakage inductor, the voltage between the terminals of the output capacitor corresponding to the output voltage (VS) of the power supply. The magnetization time (TF) and the value of the output capacitor are such that, on the resonance portion of the magnetization phase, the output voltage (VS) describes a sine wave portion and, starting from an initial value (VS0) below the median value of the sine wave, passes through said median value. |
